Ross] Ross Seal, with pup–Ommatophoca rossii [J. Libke] Australian Sea-lion–Neophoca cinerea [G. Ross] Weddell Seal–Leptonychotes weddellii [P.

OTARIIDAE AND PHOCIDAE DEFINITION AND GENERAL DESCRIPTION Pinnipeds are aquatic carnivores. They differ from other mammals in their streamlined shape, reduction of pinnae and adaptation of both fore and hind feet to form flippers. In the skull, the orbits are enlarged, the lacrimal bones are absent or indistinct and there are never more than three upper and two lower incisors. The cheek teeth are nearly homodont and some conditions of the ear that are very distinctive (Repenning 1972). Both superfamilies of pinnipeds, Phocoidea and Otarioidea, are represented in Australian waters by a number of species (Table 56.1). The various superfamilies and families may be distinguished by important and/or easily observed characters (Table 56.2). King (1983b) provided more detailed lists and references. These and other differences between the above two groups are not regarded as being of great significance, especially as an undoubted fur seal (Australian Fur-seal Arctocephalus pusillus) is as big as some of the sea lions and has some characters of the skull, teeth and behaviour which are rather more like sea lions (Repenning, Peterson & Hubbs 1971; Warneke & Shaughnessy 1985). The Phocoidea includes the single Family Phocidae – the ‘true seals’, distinguished from the Otariidae by the absence of a pinna and by the position of the hind flippers (Fig. -

Schubert, Chair Dr. Steven C. Wallace Dr. Josh X. Samuels Keywords: Ursidae, Geometric morphometrics, Ursus americanus, Ursus arctos, Last Glacial Maximum ABSTRACT Cranial Morphological Distinctiveness Between Ursus arctos and U. americanus by Benjamin J. Hillesheim Despite being separated by millions of years of evolution, black bears (Ursus americanus) and brown bears (Ursus arctos) can be difficult to distinguish based on skeletal and dental material alone. Complicating matters, some Late Pleistocene U. americanus are significantly larger in size than their modern relatives, obscuring the identification of the two bears. -
Coyote Canis Latrans in 2007 IUCN Red List (Canis Latrans)
MAMMALS OF MISSISSIPPI 10:1–9 Coyote (Canis latrans) CHRISTOPHER L. MAGEE Department of Wildlife and Fisheries, Mississippi State University, Mississippi State, Mississippi, 39762, USA Abstract—Canis latrans (Say 1823) is a canid commonly called the coyote. It is dog-like in appearance with varied colorations throughout its range. Originally restricted to the western portion of North America, coyotes have expanded across the majority of the continent. Coyotes are omnivorous and extremely adaptable, often populating urban and suburban environments. Preferred habitats include a mixture of forested, open, and brushy areas. Currently, there exist no threats or conservation concerns for the coyote in any part of its range. This species is currently experiencing an increasing population trend. Published 5 December 2008 by the Department of Wildlife and Fisheries, Mississippi State University Coyote location (Jackson 1951; Young 1951; Berg and Canis latrans (Say, 1823) Chesness 1978; Way 2007).

Periodic Status Review for the Steller Sea Lion
STATE OF WASHINGTON January 2015 Periodic Status Review for the Steller Sea Lion Gary J. Wiles The Washington Department of Fish and Wildlife maintains a list of endangered, threatened, and sensitive species (Washington Administrative Codes 232-12-014 and 232-12-011, Appendix E). In 1990, the Washington Wildlife Commission adopted listing procedures developed by a group of citizens, interest groups, and state and federal agencies (Washington Administrative Code 232-12-297, Appendix A). The procedures include how species listings will be initiated, criteria for listing and delisting, a requirement for public review, the development of recovery or management plans, and the periodic review of listed species. The Washington Department of Fish and Wildlife is directed to conduct reviews of each endangered, threatened, or sensitive wildlife species at least every five years after the date of its listing. The reviews are designed to include an update of the species status report to determine whether the status of the species warrants its current listing status or deserves reclassification. The agency notifies the general public and specific parties who have expressed their interest to the Department of the periodic status review at least one year prior to the five-year period so that they may submit new scientific data to be included in the review. The agency notifies the public of its recommendation at least 30 days prior to presenting the findings to the Fish and Wildlife Commission. In addition, if the agency determines that new information suggests that the classification of a species should be changed from its present state, the agency prepares documents to determine the environmental consequences of adopting the recommendations pursuant to requirements of the State Environmental Policy Act. -

Prior to diving, phocid (true) seals generally exhale, a behaviour thought to assist with prevention of decompression sickness. Otariid seals (fur seals and sea lions) have a greater reliance on their lung oxygen stores, and inhale prior to diving. -
